If you couldn’t refresh feed Instagram, it could be due to a few reasons: on the users’ side, this can be due to a poor or intermittent connection to the internet, or an older version of the application installed on their device; on the part of Instagram there can be problems with servers. Make sure that you are connected well to a wireless network or data connection and then try relaunching the application. If the problem remains, then it is possible that you should search for an update on the particular application or go onto Instagram’s official status page to realize if the period is experiencing extensive complications.
